[Expert consensus on the diagnosis and treatment of respiratory diseases exacerbated by nonsteroidal anti-inflammatory drugs （2024, Chengdu）].

Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease （N-ERD） is a chronic respiratory disease characterized by eosinophilic inflammation, featuring chronic rhinosinusitis （CRS）, asthma, and intolerance to cyclooxygenase 1 （COX-1） inhibitors. The use of these medications can lead to an acute worsening of rhinitis and asthma symptoms. This condition has not yet received sufficient attention in China, with a high rate of misdiagnosis and a lack of related research.

Chinese Expert Consensus on the Use of Biologics in Patients with Chronic Rhinosinusitis (2022, Zhuhai).

Background: Chronic rhinosinusitis (CRS) is a common inflammatory disease in otolaryngology, mainly manifested as nasal congestion, nasal discharge, facial pain/pressure, and smell disorder. CRS with nasal polyps (CRSwNP), an important phenotype of CRS, has a high recurrence rate even after receiving corticosteroids and/or functional endoscopic sinus surgery. In recent years, clinicians have focused on the application of biological agents in CRSwNP.

Establishment and validation of M1 stage subdivisions for de novo metastatic nasopharyngeal carcinoma to better predict prognosis and guide treatment.

Background: To better manage patients with de novo metastatic NPC (mNPC) including easily identifying individuals' survival outcomes and accurately choosing the most suitable treatment.

Materials And Methods: Three independent cohorts of mNPC patients (a training set of n = 462, an internal prospective validation set of n = 272 and an external prospective validation set of n = 243) were studied. The radiological characteristics of distant metastases, including number of metastatic locations, number of metastatic lesions and size of metastatic lesions, were carefully defined based on imaging data.

The complete mitochondrial genome of the common buckeye Junonia coenia (Insecta: Lepidoptera: Nymphalidae).

The complete mitochondrial genome of the common buckeye Junonia coenia (Insecta: Lepidoptera: Nymphalidae) was reconstructed from whole-genome Illumina sequencing data with an average coverage of 1213×. The circular genome is 15 222 bp in length, and consists of 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs) and one D-loop region. All PCGs are initiated with ATN codons.

[Derivative synchronous fluorimetry for determination of synthetic food dyes in food].

The first order derivative synchronous fluoremetry was proposed for simultaneous determination of sunset yellow and ponceau 4R The effect of different experimental conditions, such as different pH for character of fluorescence spectra and the choosing of the optimal wavelength difference were studied. It was showed that the zero-crossing points were at 313. 6 nm for ponceau 4R and at 302.

[Resection of parapharyngeal neoplasms via styloid diaphragm approach].

Objective: To evaluate the surgical technique and efficacy of the resection of parapharyngeal space neoplasm via styloid diaphragm approach.

Methods: Thirty-three cases underwent the resection of parapharyngeal space tumors via styloid diaphragm approach from Jan 2005 to Jan 2011 were reviewed. Of the cases, 28 were with benign tumors treated by surgery alone, and 5 were malignant tumors treated by surgery plus postoperative radical radiotherapy.

Endoscopic surgery of cavernous sinus tumors originating from the extradura.

In the present study, we explored the effects of various endoscopic approaches in patients with cavernous sinus (CS) tumors. Five endoscopic approaches, including the endoscopic transseptal transsphenoidal approach, extended endoscopic transseptal transsphenoidal approach, extended transnasal transmaxillary approach, extranasal extended maxillary sinus approach, and endoscopic transnasal transpterygoid approach, were selected for the resection of CS tumors from 36 patients. Thirty gross total tumors and 6 subtotal tumors were removed.

[Synthesis of maleic anhydride-acrylamide copolymer and study of its adsorption properties by ICP-AES].

A novel adsorbent was prepared with maleic anhydride and acrylamide as functional monomer, N, N-methylenebisacrylamide as cross-linking agent, and ammonium persulfate as initiator through aqueous polymerization reaction. The adsorbent was characterized by Fourier transmission infrared spectra (FTIR) and Thermogravimetry (TG). The adsorption properties and selectivity properties were investigated by inductively coupled plasma atomic emission spectrum (ICP-AES).

Effect of orange peel essential oil on oxidative stress in AOM animals.

The processing parameters of pump speed, inlet air temperature, outlet air temperature and homogenization pressure were evaluated. Encapsulation efficiency is high with a satisfied releasing rate. Then, acute otitis media (AOM) animal model was built and diet containing orange peel essential oil microcapsules were administrated to AOM animals.

[Endoscopic posterior septectomy for patients with nasopharyngeal tumor].

Objective: To explore the techniques, advantages and disadvantages, indications and cautions of a surgical approach for the resection of nasopharyngeal tumor.

Methods: Ten cases with nasopharyngeal tumors were recruited in this study, of them, 3 cases with residual nasopharyngeal carcinoma after chemoradiotherapy, 2 cases with cavernous angioma, 2 cases with benign mixed tumor, 1 malignant mixed tumor, 1 adenoid cystic carcinoma, and 1 chordoma. All patients underwent endoscopic resection of posteroinferior quarter part of nasal septum, and then the removal of nasopharyngeal tumors through bilateral transnasal approach.

Endoscopic resection of chordomas in different clival regions.

Conclusion: The endoscopic approaches developed for the treatment of the chordomas according to the different clival location provide the possibility for more complete tumor resection with maximal preservation of anatomic structures and reduction of the overall incidence of complications.

Objective: The endoscope has recently been applied in patients with chordomas, but rare studies report the various endoscopic approaches in the treatment of chordomas in the different regions of clivus. In this study, the authors present their experience with these techniques in patients with chordomas.

[Prevention and management of complications of endoscopic surgery for nasal-skull base neoplasms].

Objective: To analyze the surgical complications of endoscopic nasal-skull base surgery. The secondary objective was to propose the preliminary strategies for prevention and treatment of complications.

Methods: One hundred and thirty two patients with nasal-skull base tumors undergoing endoscopic or endoscope-assisted surgery were included in this study.

[A preliminary study of endoscopic transoral trans-posteriorwall pharynx resection of hypo-clivus chordoma].

Objective: To introduce a endoscopic surgical approach for hypo-clivus chordoma, and to explore the clinical value of the endoscopic resection of hypo-clivus chordoma.
